Raypak Electric E3T Heater 18KW | 100-10000665

Raypak E3T Electric Pool & Spa Heater 18kW | 100-10000665

The Raypak E3T 18kW electric pool and spa heater delivers advanced digital precision, quiet performance, and long-term reliability for both residential and commercial installations. Using solid-state electronic components and titanium heating elements, it ensures corrosion resistance, stable water temperature, and consistent operation—even in saltwater pools. The result is a powerful yet compact system designed for efficient, trouble-free heating in modern pool environments.

Housed in a compact NEMA 3R-rated cabinet, the E3T installs easily in confined spaces indoors or outdoors. Integrated safety features—including flow, temperature, and freeze monitoring—continuously protect the heater from dry-fire damage, over-temperature conditions, and rapid cycling. The intuitive LCD interface provides live data on inlet and outlet temperature, flow rate, and system diagnostics, enabling fast, clear visibility for operators and technicians.

The E3T Series meets California Title 24 energy-efficiency requirements, ensuring future regulatory compliance and eco-friendly operation. With the 2026 energy updates approaching, Raypak’s E3T lineup helps pool owners stay compliant while maintaining consistent heating performance and lower operating costs—all backed by Raypak’s reputation for durable engineering.

Intelligent Digital Control System

At the heart of the E3T lies Raypak’s state-of-the-art electronic control platform, giving users precise temperature management and advanced system insight. Unlike older blinking-light diagnostic systems, the 12-character full-text LCD display (available on 18kW and 27kW models) provides detailed operational information, real-time alerts, and clear fault messages for easy service and setup.

The E3T’s two-wire automation connectors make integration simple with pool control systems, allowing users to automate heat cycles or manage heater schedules remotely.

Comprehensive Protection Systems

Raypak engineered the E3T for long-lasting dependability under fluctuating water and environmental conditions. Multiple protective mechanisms continuously monitor performance, minimizing risk and maximizing lifespan.

Built-in safety features include:

• Automatic Flow Monitoring: Shuts off if flow rate is below or above the 15–60 GPM safety threshold.

• Low-Temperature Operation Logic: Prevents thermal shock by gradually adjusting heating when cold water enters.

• Freeze Shutdown Protection: Disables operation at 32°F (0°C) to safeguard the system from freezing.

• Element Performance Monitoring: Detects early wear or faults in heating elements for proactive maintenance.

• Time Delay Restart (1 Minute): Prevents rapid cycling and overheating to preserve system integrity.

Together, these advanced features deliver reliable heating performance while protecting the unit from damage and inefficiency.

Engineered for Durability & Harsh Conditions

Each Raypak E3T features titanium heating elements for unmatched corrosion resistance and scale prevention. The reinforced, weather-resistant NEMA 3R-rated enclosure allows installation in exposed outdoor pads or enclosed mechanical rooms without risk of deterioration.

Ideal for small in-ground pools, therapy or resistance pools, and spas, the E3T provides dependable, consistent heating where uptime is essential. With strong protective design and advanced digital technology, it remains one of the most robust and efficient electric heaters in its class.
